FBI: 'We Will Go To The Ends Of The Earth To Find' Those Responsible For Boston Marathon Bombings

In a wide-ranging press conference that offered little new hard
details on the Boston Marathon bombings, FBI Special
Agent Rick DesLauriers pledged that the U.S. will go
to "the ends of the Earth" to identify those responsible for the
attacks.

"This will be a worldwide
investigation," DesLauriers said.

Massachusetts Gov. Deval
Patrick said that more than 150 people have been injured in
the bombings, including three confirmed dead. He
also also immediately dismissed reports that more
undetonated devices had been found after the attacks — comments
that were echoed by ATF
official Gene Marquez.

It was a press conference that
was at-times emotional, as Boston Mayor Thomas Menino — speaking
from a wheelchair after a recent leg fracture — declared that
"Boston will overcome."

"Yesterday, terror was brought to the city of Boston,"
Menino said. "This
is a tragedy, but Boston is a strong city,"

Boston Police Commissioner Ed
Davis said that the investigation was the most complex the Boston
PD had ever undertaken.

"We are in the process of securing the most complex crime scene
in the history of our department," Davis said.

Overall, little new information
has emerged about the explosions over the past 10 hours. Late
last night,police reportedly searched a home in Revere, Mass., a suburb of
Boston. The Revere Fire Departmentwrote on its Facebook page that its firefighters responded to
the scene in connection with a "person of interest," along with
multiple law enforcement agencies that included the FBI.

DesLauriers had little new information, saying that the
investigation is ongoing and that there were no new known
additional threats. DesLauriers also wouldn't comment on any
materials used in the bombs or whether the FBI had anyone in
custody.

"I'm not going to say who might or might be in custody right
now," he said. But Davis later said that "no one is in custody."
